IPC: F23N5/10
Filed: 1978-10-12
Abstract: PURPOSE:To cut off a vlave opening circuit at a proper time at the time of begining by opening a switch for the valve opening circuit closed at the begining by an electronic control circuit operated when a terminal electromotive force of a thermocouple has become to be high enough. CONSTITUTION:When a valve for a pilot-burner is opened and an electric source switch 01 is closed, a solenoid 30 is energized and a switch 31 is closed, thereafter, sub-switch 32 is opened a little bit later. By the closing operation of the switch 31, a valve opening circuit B is closed and an electromagnetic holding valve 2 is opened, thereby, gas is supplied to the pilot-burner. At the same time, an electric igniter 4 provided in parallel is operated and the pilot-burner is ignited. When an electromotive force is generated from a thermocouple heated by the pilot burner and the output thereof arrives at a necessary value, a variation detector 5 and a converter 6 detect it and the valve opening circuit B is opened while a security circuit is closed, thereby, the electromagnetic holding valve is held in open.

Title: Color registration adjusting method in image forming apparatus
Inventor: KIM NAM-RYOUNG
IPC: G02B26/10
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a color registration adjusting method in an image forming apparatus capable of quantitatively adjusting the color mis-registration of laser beam in a main scanning direction. SOLUTION: When a pulse width detected by comparing a pulse width detected with respect to the edge of a photosensitive belt with an expected pulse width is smaller than the expected pulse width, the detected pulse width is set to a scanning start signal (synthesized edge signal), and a value obtained by subtracting a predetermined value from the present expected pulse width is set to next expected pulse width and. When the detected pulse width is larger than or same to the expected pulse width, the expected pulse width is set to a scanning start signal (synthesized edge signal), and it is judged whether or not a pulse count value is less than an offset value in order to set the next unexpected pulse width.

Title: Switching power unit
Inventor: TOTSUKA SHOJI
IPC: H03K17/695
Filed: 1995-05-24
Abstract: PURPOSE: To improve the turning-on/off characteristic of a switching element by controlling the turning on/off of a DC voltage by means of a switching element by superposing a voltage which turns on/off the DC voltage upon the control voltage, based on the control voltage. CONSTITUTION: A control circuit 3 sends a pulse and, when a voltage is 0V, an electric current flows through a diode 19 and the voltage of the current drops through resistors 16 and 17. When a transistor(Tr) 13 is turned on/off, another Tr 12 is turned on/off and superposes a DC voltage upon the gate of an FET. When the output of the control circuit changes to +V from 0V, therefore, a quickly rising voltage is supplied and the efficiency of a switching power unit can be improved by reducing the loss of the power unit, because the Tr 12 is also turned on/off and superposes a DC voltage upon the gate of the FET and the input capacity of the gate is discharged through the Tr 12.

IPC: G01B11/24
Filed: 1990-05-15
Abstract: PURPOSE:To measure a surface shape to be measured having a large aspherical amount with high accuracy in a short time free from an influence of a gradient angle compensating mechanism by coherently measuring the surface shape of a surface to be measured with a reference surface fixed to an end face on the same plane as the surface to be measured used as reference. CONSTITUTION:A coherent beam from a light source 18 is, through a gradient angle compensating mechanism 22, incident to a Fizeau's reference device 23 having a semitransparent film 27 on a side of a surface 25 to be measured. The incident beam is divided into a reflection beam and a transmission beam by the transparent film 27 formed as a Fizeau's reference surface, wherein the transmission beam is converged on the surface 25 to be measured by an objective lens 24, reflected to pass through the lens 24 again to be overlaid on the coherence as a reflection beam on the semitransparent film 27, and reversely proceeds in the compensating mechanism 22 to be coherently measured in an interference fringe measuring unit 26 via a deflection beam splitter 51. Then the compensating mechanism 22 is moved in a direction of an arrow indicated in the figure according to a signal from a light sensor built into the measuring unit 26 to compensate the gradient angle. Therefore when the compensating mechanism 22 is operated to shift the beam laterally in a direction perpendicular to an optical axis 29 to be measured, interference fringes to be observed by the measuring machine 26 are hardly affected.

IPC: F23C99/00
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To remove smoke soot and effectively utilize it by a method wherein a dust collector is arranged at a stage followed by an air preheater, smoke soot is collected, and returned to a boiler and a carbon content contained therein is caused to effect recombustion. SOLUTION: Combustion exhaust gas generated in a boiler 1 contains smoke soot removed by a dust collector 3 and the smoke soot is returned to the boiler 1 for recombustion. An electric dust collector and a cyclone are used as the dust collector 3. Combustion exhaust gas flowing out from the dust collector 3 heats air supplied to the boiler 1 for combustion by a blower 6 and the combustion exhaust gas itself is cooled and fed to an exhaust gas treating device 5. The exhaust gas treating device is provided with a desulfurization device 5 and a chimney and smoke soot is discharged to the atmosphere. Since the carbon component of smoke soot returned to the boiler 1 is reburnt, combustion efficiency is improved. Further, NOx in exhaust gas is reduced and the generation of NOx is reduced.  Further, when the generation of N0x is reduced by a denitration device, an amount of using ammonia is decreased.

Title: Control system for turning off of power supply
Inventor: NAKAO SHINJI
IPC: G06F1/26
Filed: 1988-05-23
Abstract: PURPOSE:To evade the waste of time during the debugging or the fault check of hardware by using a setting switch which performs the changeover between a contact that turns off a device power supply immediately after a power switch is turned off and a contact that turned off the power supply via the sequence control. CONSTITUTION:A setting switch 13 is added to a power supply circuit 5 containing a power ON/OFF control part 7 which performs a power ON/OFF sequence via the firm control. A normal power OFF sequence is carried out when a power switch 6 is turned on while the switch 13 is kept to OFF. While the supply of power is immediately cut off to a device when the switch 6 is turned off while the switch 13 is kept to OFF. Thus it is possible to avoid the waste of time during which the switch 6 is manually turned off and the supply of power is actually cut off when the hardware is debugged or undergoes the check of its fault.
